To all iff/30m 'it may Centern:

Be it known that l, Mornus S. lll/RIGHT, a citizen of the United States, residing at lVoreester, in the county of -Worcester and Siate of Massachusetts, have invented certain new and useful Ii'npriivements in EX haust lflpparatus, of which the following is a speeifieation, reference being had therein to the aeeompanying drawing.

This invention relates to an exhaust apparatus and though susceptible of a variety ot adaptations il. designed primarily for use in connection with pneumaticy cleaning systems. wherein is employed a nozzle or the like adapted to play over a surface to be eleaned, the apparatus operating to draw into ihr maf'hine the dust laden air and to exhaust the air therefrom..

More ifm'tieularly, the invention includes a plurality oi' pumps, conveniently power armati-fl,.with novel means for supporting the .same upon ay suital'ile wind ehest, vaeuum Chamber or the like.

li'urther, the invention comprises novel instrumentalities whereby the pum )s may be separately removed as indepent ent and complete units. permitting each pump tu loe replaced a t will Ywithout interfering with the associated pumps or other parts ot' the apparatus, und to atlioid. ready aeeess to tho valve mechanism of the vacuum chamber or the likeI which is in eommunieation with the pumps.

The .invention also includes improved power aetiiatinor means for the pump and supporting mee anism for the latter.

Again the in'iention embraces' a novel form of vaeuum Chamber or wind Chest with simple and eliective means for guarding the valve mechanism thereof from the dust. and preventing the passage of the dust into the pumps from said chamber.

Other impro\.'ements, including novel details in the eonstiuction and arrangement ot the paris. thereby forming a Simple, ix'iraeli- Pal. more etlieient and inexpensive nxerhanism for the purpose stated, u'ill he more partieularly brought out in the following speeitiration, whirh for a clear and eoniplele understanding of the invention should he considered Yin connection with the aecompanying drawings forming a part hereof, and wherein is disclosed, for the purpose of illustration, u convenientI and satishietory embodiment of the invention.

In the drawings: Figure l is a side view in elevation, the parts being shown in section for the purpose of illustration. Fig. 2 is a top plan view. Fig. 3 is an en?? elevation. Fig. 4 is a detail perspective view ot' a removed part of the apparatus enlarged. p Referring now more particularly to the dra-Wings wherein like reference numerals refer to similar parts throughout. the several views, 1 is the hase of a wind chest, vacuum chamber or the like, the latter also having sides 2 a rear end 3 and a top t, the said top resting upon the upper surface of the sides 2 and end 3 and secured to the hitter in any suitable manner. A removable front 5 is provided for the .front end of the vacuum chamber, the same overlying the top7 bottom and side walls just referred to, and a suitable packing 6 being interposed between the ends of said walls and the removable front 5, the packing being conveniently secured to the removable front7 5. Also secured to the removable front Wall 5 is a drawer 7 in which latter may he mounted a suitable filtering bag 8. The removable front wall 5 has an opening 9 therein adapted to register' with the open end of the bag and in which said opening adapted to be mount ed a tulie or the like l() for connection with a suitalile nozzle or the like adapted to play over a surface to be cleansed.

Positioned upon the top 4 of the vacuum chamber 1 are al'iluralit-y of pumps, the same being conveniently arranged in pairs and there heilig a pair atljaeent each end of the uiirl ehest. ,Hach ot these pumps to gether u ith the Supporting mechanism theretor are substantially the same in euch in tonie and a, description oi one iviil sutiiee 'or the others. The pumps .anprrfv on inner relatively fixed section il., a movable seetion l? hinged to the relatiiely iixetl seetion li in any lesirel manner as at lll, the said iw-tions being etmnr-fted hy the nsualdiaphratna ll. 'The fixed Seetion of the pumps has an opening intermediate its ends. shown at i5 for the admission or air and the movi ulile aeetion has an opening :ir plurality of i openingsv 1C for the exhaust, the said openl ing l heilig normally closed by a flap valve l nirznher 3T mired at its upper end to the louter suri'aee of the member 12 and spring held as at i8 at' its lower end tosaid member 1Q. The flap vulve member 17 is Conveniently of Very llexiull lriaiQlnl, the Saflie liilginforced as by substantially noneyielding cils I9, the latter bein positioned on the valve member 17 one a jacent each of the openings 16. Elongat'ed metallic brackets or supports 2O are provided for the pum s, the saine being preferably inclined npwar` y and inwardl and scoured to the outer face of the fixe section 11 as bv removable screws 2l. The said bracket members 2O connect with and conveniently are made integral with the tubular conduits 22 which later terminate in offset feet 23 resting upon the to 4 of the vacuum chamber. and secured to t e latter as by removable screws 23. The conduits 22 establish a vertical passage way 24 and one wall thereof is cut away at 25, thereby forming a transverse opening connectingr with the opening 15 in the fixed member 11 of the pump. The top 4 of the vacuum chamber is provided with openings 26 one for each conduit 2Q, and arranged to normally close said openings 26 is a disk valve 27 one for each opening, said valve adapted to resty on tbeouter surface of the top wall l and having a projectin stern 28 slidable in an aperture of a va ve bracket 229 also positioned on the top Ll of the Ivacuum chamber. The disk-shaped valves 27 have a suitable reinforcing backing 30 adapted to contact with the top of the bracket 29 to limit the opening movement thereof.

Positioned upon the top 4 of thevacuum chamber is a suitable motor 31, the same being` conveniently arranged intermediate the ends of the vacuum chamber between the pumps at the ends thereof, thel said motor having projecting from one side thereof a drive shaft 32 extending transversely of the vacuum chamber and having mounted there on for movement therewith a drive pinion :lil which latter is arranged to Iilceh With a gcair Wheel 34 mounted upon whatinay be te neil the pump drive shaft 33 which latter extends across the, machine hint is suitably supported adjacent oppmitc ends in bearings 5G mounted upon longitudinally e tended supports 37. The Suid supports lli' restat their opposite ends' upon oll'set llangcs o8 adjacent the upper envie; ofthe brackets "20, and beingr secured in position by removable bolts 3U passing through the sides of thelirafkets l0 and the ende: of the supporte.y 3T as more clearly Shown in Fig. l. The pump drive shaft S5 in the naturey of a crank shaft having crank members l0 and -lt' projecting rcepcctirclv in ililfcrcnt directions and connected to said crank:y are sui* ale pilnian rods, ll one for erich movA abli .section of the pumps, 'the ,-onfiriii'tion being: mii-h that a pump at one t'nfl oi' the machinii-e in 4`chstA '-lial alincinrt with :i pump al, tht3 oppo. ite cnil ol the machine, and the rofl Lll for the movable Section of one l lt .ail pumps' bitiirczil'ed at its end to forni a yoke l'or the icijfeption of the terminut of the other rod, said terminal mi biiyurcated portion being slet-vedi upon tlfcrnk as clearly illustrated in 'l f movablesections of the pumps have w. thereon a bracket inclnlg'cr which c the outer surface thereotl :unl r e reinforcement therefor thi 'il members being; designated by the hmm 42 and having a, flange lzf" ovcilvii; i per edge of the movable evelien l2. and :iw having an upwardlv extended portion iii constituting a hearing #il for the oder uw of the rods all. lr will be note-l that the bracket 4i! with the extension l-l, elif-:iwi conveniently :formed ot metal constitute e very substantial support for the operating pitman rode, and position the sonne aliiwe the upper end oit the metallic supporting brackets 2O and longitudinally extending Supports 37, iermitiing tree back and forth f}the movable sections' 1Q. From the description thus far and from an inspection of Figs. l. and 2 of the draw ings, it Will be observed that in operation, movement being imparted to the p rods; through the medium of the motor unil the parts connected to the drive 3C. the movable sections l2 of the pumpe :com outwardly about their hii'iged connection El the'llap valves 17 will be held elosw, while the disk valve Q7 will be automatica, zj; raised by the suction created thereby drawing the dust, laden air'through the coni tion l() into the tiltering bag S and the f' v stantiaily cleansed air through the. opening 2t', into the chased passage vv ay -l :mit iin :ii-i into the pump through the opening in. le the movable section ot' the pump is reverse moveniem, that, invieritly. valve 2i" will automa ellyv real therein' shutting ett the cominuiiication between lift; vacuum chamber and the conduit EL', :init the flap valve l? will be opened. ther d' permitting the air to efghnustfrom the pun through the openings 1G. 'the pumpe rc so positioned and the drive connections liir the movable sections so arranged that :is the mo 'able section of one pump et one enel of the machine is moved in one direction t movable Section of the cooperating pump at the opposite end of the machine. will n: ve in a reverse direction, and the movable tion of :1 succeeding pump atene emi el the machine will move in a reveree direction ik; the movable section of the adjacentpump at the same end of the niachine. The #uit is that. a continuous suction is ne. in tained in the vacuum chamber, and th' tion will be very powerful. The brackets '30 not only constitute a verf; firm ind euh stantial reinforcement for the lifted. eretici: of the connected pump but, as vwl". :i stentinl support for the longitmlfufi porting members 37, and also duit tor the passage. of the lili;

i weil il i) dll vacuum chamber to the pumps. Again the inclosed conduit 22 constitutes a protecting medium for the movable valves 27 and affords a direct passage way for the air from the opening 26 of the vacuum chamber to the opening of the pump, It will also be appreciated that the pumps themselves are free from -connection with the vacuum charnber, and are supported through the medium of the metallic bracket members with the result that by removing the securiiw means 23 and the securing means 39, the said brackets with the connected pump may be bodily removed as an independent unit for access either to the pumps or to the valves 27. This constitutes an important feature of the invention, and even should one of the' screws 48. The diaphragml with its conneeted frame is slidably mounted upon supporting guides or runways 49 secured to the Walls of the vacuum chamber, and it will be noted that the diaphragm may be moved from the open end of the machine by sliding the samealong tlierunway 49, after removing the front wall 5, as previously described.

,Since the diaphragm extends substantially fromf end to, end and 'side to side of the vacuum chamber, the other parts of the machine will be protected from the admission of dust, etc., and the'detachable characteristic of this diaphragm makes it possible to lreadily clcansethe same, or to replace as r occasion demands.
